WIRE-FENCE MACHINE.

SPECIFICATION forming part of Letters Patent Nd. 567,123, dated September 8, 1896.

Application filed December 2,1895. Serial No. 70,834. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. CAMPBELL, of Albion, in the county of Orleans and State of New York, have invented a certain new and useful Improvement in Wire-Fence Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

My improvement relates to machines for making wire fence in the field.

It also relates to that class in which a series of gears are used corresponding in number with the number of longitudinal strands in the fence, and a set of twister-heads are used, being movable from one gear to another by reversely-acting slides.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of the machine, looking in the direction of arrow 1, Fig. 3. Fig. 2 is a side elevation looking in the direction of arrow 2, Fig. 3. Fig. 3 is an enlarged cross-section in line 0050 of Fig. 1. Fig. 4 is an enlarged side elevation of one of the gears and the connecting twister, looking in the direction of arrow 2 in Fig. 3. Fig. 5 is an end elevation of Fig. 4, looking in the direction of arrow 3 of the last-named figure.

A indicates the standard or frame of the machine attached to a base having trucks which run on a platform in the usual manner. 13 B B B are a series of spur-gears attached thereto and engaging together, their number corresponding with the number of longitudinal strands a a of the fence. These wires CLCI/ pass through the center of the wheels and through tubesb b in the usual manner. One of these gears B has a bevel-gear B, with which engages abevel=pinion C, Fig. 3, resting on a cross-shaft c and provided with a crank 01, by which it is operated. By this means all the gears are operated at once. The face of each of the spur-gears B B has two parallel flanges ff, which form guides for the inner ends of the twister-frames, as will presently be described. In the position for shifting the twisters from one gear to another these flanges stand vertically and in alinement in all the wheels. Each of the gear-wheels also has a large rectangular guide-frame D rigidly attached thereto and projecting outward at right angles, said frame consisting of upper and lower horizontal bars g g and a vertical connecting outer cross-bar h, the latter having flanged circular ribs h h at its edges, as shown in the plan view, Fig. 3. The frames D serve as guides and holders for the twisterframes as they pass-from one gear to another.

E E are the twister-frames, the same being large, flat-sided, and of rectangular form and fitting the flat sides of the guide-frames just described. The twister-frames are arranged to slide up and down on opposite sides of the guide-frames. The inner ends of the twister-frames Ehave bearings it, which rest inside the guide-flanges f f on the faces of the gears. To the outer ends of the twisterframes are-attached the twister-heads E E, each-consisting of a segment approximating a half-circle, standing at right angles to the frame and provided with a beveled groove is forreceiving the curved edge of the bracket by which the twister is raised or lowered. The twister-heads also have concave bearings jj, which slide up and down on the circular ribs h h of the guide-frames D, by which means the outer ends of the twister-frames are retained in place. If desired, the con-= nection may be reversed, the brackets being grooved and the twister-heads having bearings to fit therein- Said twister-heads are also provided with outwardly-proj ecting lugs Z Z, Fig. 3, pierced with holes, through which pass the filling-wires from the spools F F, said filling-wires also passing through the twisterheads themselves. The spools F F rest on studs m 'm, projecting from the sides of the twister-frames, and tension thereon is pro duced by springs 'n 'n or by other means.

G G are arms attached to the main standard A, projecting outward on each side and provided at their outer ends with bearing-blocks p p, which form guides to the reversely-opcrating slides H H, which carry the twisterheads up and down. ,Said slides consist of long bars which slide between arms 1) p of the guides 10 19. To the slides are attached the brackets I I, which hold the twister-heads. The inner edges of the brackets are concaved to fit the circle of the twister-heads, by which means the twister-heads are allowed to revolve chines now in use the slides are connected 1 with the rock-lever by simple connecting rods 1 or pitmen attached by pivots at both ends. Instead of such arrangement I employ on each side a bearing L, fast to the slide and provided with two forked ends 5 8, through which passes the connecting-rod 25, attached to the end of the rock-lever.

the bearing L, with the slide attached, can be raised and lowered. arran ement is to adjust the slide H up or down to bring the two brackets in true alinement with each other, so that the twisterhead will turn properly between them. Heretoforedifficulty has been experienced in keeping' the brackets in coincidence, so that the twister-heads will turn easily, owing to the loose connections of the pitmen to the slides. By the means above described they can be adjusted with great accuracy and with little trouble. i V

A special feature of this invention is the rectangular guide-frame D, of large size, projeeting bodily outward from the face of each On the lower end i of the rod t are two nuts u a, by which means The object of this gear and forming a broad surface, on which the twisterframe E slides, the latter also being large and having a broad bearing-surface to fit the guide-frame. By this means so broad a bearingsurface is attained that the twisters are held firmly to place during their rotation, and the filling-wires are wound un- 5 its support is of small size.

" cramping or yielding under action.

der strain without danger of the twisters The action is much more effective than in those machines where the bearing of the twister against This broad bearing of the twister-frame enables it to move up and down in a true line, thereby shifting from one wheel to another without striking any impediment or binding.

Having described my invention, What I f claim as new, and desire to secure by Letters Patent, is-- In a wire-fence machine, the combination,

with the gears 13 B and reversely operating slides H H, of the rectangular guide-frames D D projecting bodily from the gears, and the corresponding rectangular twister-frames E E resting in contact therewith, and having twister-heads at their outer ends, the guideframes provided with the flanged ribs h hf, and the twister-heads with bearings j j fitting over said ribs, as shown and described and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
